It’s no accident that the movie poster for What If places good friends Wallace and Chandry at a diner.

The film is clearly trying to be the When Harry Met Sally for this generation…and does a decent job.

Daniel Radcliffe and Zoe Kazan are quirky and appealing, their friendship believable, their banter quick and smart.

She has a boyfriend (who made me laugh), and Daniel has emotional baggage — plus best friend Adam Driver of Girls who has huge energy…and is huge standing next to Daniel (which is pretty funny right there).

This is a rom-com, so there are misunderstandings, yearning, romantic postcards (in this day and age), implusive international flights, fist fights, and at least two weddings — babies, too.

When I was walking through baggage claim tonight in Terminal C at LaGuardia, I noticed a little boy — four or to five years of age, I’m guessin? — who was closely examining the wall-mounted water fountain.

His father stood patiently to one side as his son pushed the button again and again, seemingly fascinated by the stream of water he was summoning forth.

“That is so cool,” the boy said.

“It is really cool,” his dad replied.

And then we all smiled at each other and shared the moment, which was really cool, too.

“I’ve dropped my cellphone in water. Email me until I get it replaced.”

This hasn’t happened to me yet. But as recently as last month, I heard similar tales from family and friends. And I am always sympathetic (to keep karma on my side).

Today I offer a possible solution.

It’s called DryBox Rescue, a service offered by authorized dealers around the country. Your soggy cellphone is placed in a patent-pending drying chamber. The moisture is then removed — at the molecular level — in less than 30 minutes.

It also works on other small electronic devices that are drawn to the toilet and sink — mp3 players, cameras, GPS units, etc.

Full disclosure: I’ve never used this service; I’ve just read about it in an airline magazine. But it sounds like a much better option than 1) rice or 2) throwing away your pricey smart phone.

So, give it a look. Other than the rather unfortunate name, I think it shows promise.
